A team of four aliens escape their exploding home world only to crash land into a move-in ready home in suburban America. They are evenly split on whether Earth is awful or awesome. Korvo (Justin Roiland) and Yumyulack (Sean Giambrone) only see the pollution, crass consumerism, and human frailty while Terry (Thomas Middleditch) and Jesse (Mary Mack) love humans and all their TV, junk food and fun stuff. Their mission: protect the Pupa, a living super computer that will one day evolve into its true form, consume them and terraform the Earth.
Some autobots are captured. The remaining Autobots team up with some rebels to free their friends, the rebels know all the weaknesses of their enemies machines. They merge with the Autobots to become Headmasters to free their friends.
